Submerged Arc Welding (SAW) shields the weld arc using a granular flux fed
into the weld zone forming a thick layer that completely covers the molten zone
and prevents spatter and sparks. It also acts as a thermal insulator, permitting
deeper heat penetration.
The process is obviously limited to welding in a horizontal position and is widely used for relatively high speed sheet or plate steel welding in either automatic or semiautomatic configurations. The flux can be recovered, treated, and reused.
Submerged Arc Welding provides very high welding productivity....4-10 times as much as the Shielded Metal Arc Welding process.
